Efficient full state tomography of the orbital angular momentum states of light using Helicity sorter
Joel M. Sunil, Sandeep K. Goyal
Orbital angular momentum (OAM) of light is a promising degree of freedom for quantum communication and quantum computation. However, efficient methods to transform and measure OAM…
Deterministic preparation of optical qubits with coherent feedback control
Amy Rouillard, Tanita Permaul, Sandeep K. Goyal +1
We propose a class of preparation schemes for orbital angular momentum and polarisation qubits carried by single photons or classical states of light based on coherent feedback con…
Storing vector-vortex states of light in intra-atomic frequency comb
Chanchal, G. P. Teja, Christoph Simon +1
Photons are one of the prominent candidates for long-distance quantum communication and quantum information processing. Certain quantum information processing tasks require storage…
Ancilla-Assisted Protection of Information: Application to Atom-Cavity Systems
Rajeev Gangwar, Mohit Lal Bera, G. P. Teja +2
One of the major obstacles faced by quantum-enabled technology is the environmental noise that causes decoherence in the quantum system, thereby destroying much of its quantum aspe…
Implementation of discrete positive operator valued measures on linear optical systems using cosine-sine decomposition
Jaskaran Singh, Arvind, Sandeep K. Goyal
Positive operator valued measurements (POVMs) play an important role in efficient quantum communication and computation. While optical systems are one of the strongest candidates f…
Quantum theory of statistical radiation pressure in free space
Navdeep Arya, Navketan Batra, Kinjalk Lochan +1
Light is known to exert radiation pressure on any surface it is incident upon, via the transfer of momentum from the light to the surface. In general, this force is assumed to be p…
